One-click Tethered Jailbreak Boot iOS 4.2.1 Redsn0w

RedSn0w 0.9.6rc7 is now available with one-click boot option for tethered iOS 4.2.1 jailbreak devices. What this means is that with RedSn0w 0.9.6rc7, there’s no need to select firmware files each time you need to boot your tethered jailbreak device.

Dev Team explains:

We’ve updated redsn0w to include “one-click” support for those of you running the tethered 4.2.1 jailbreak. Using command-line arguments, you can now bypass the screens you’d normally see as you use redsn0w to “Just boot tethered for now”.

The available command line arguments are:

-j to ask redsn0w to “Just boot now tethered for now”
-i <filename> to specify your reference IPSW
-o for old-bootrom iPod touch 2G and iPhone 3GS
-b <filename> to specify your own boot logo png

For example, redsn0w for Mac to do a tethered boot of an iPod touch 4G jailbroken at 4.2.1:

open ~/Desktop/redsn0w.app -args -j \ ~/Desktop/iPod4,1_4.2.1_8C148_Restore.ipsw

This assumes both redsn0w and the IPSW are on your OS X desktop, so use vas necessary!

Mac users: Change the permissions of your custom *.command files to allow execution.

Windows: Included in the zip is an example script file that you can double click on to launch redsn0w like this (the Windows example assumes everything is in C:\).

Note:

• Make sure you have the latest iTunes 10.1.1 installed.
• Windows 7 and Vista users should use Redsn0w in “XP Compatibility Mode”.
• All the required download links are given at the end of the post.

This should help ease the pain of the tethered jailbreak until @comex comes up with a 4.2.1 untether.
